i Specification forming part of Letters Patent No. 57,09] dated August14, 1866.

To a/ZZ whom 'it mayconcem: T

`Be it known that I, WINEIELD B. 00E, ot' West Meriden, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Apparatus for Spreading Mastic` Roofing; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which `will enable others skilled in the art to make and usethe same, reference being had to the accompanying drawings, forming partof this specification, in whicht,

Figure lis a vertical longitudinal section of my `improved apparatustaken through the line aux, Fig. 2. \Fig. 2 is a rear-end view of the`same,part of the spreading-board being broken `away to show thearrangement of the parts.

Similar parts.

My invention has for its object to furnish an improved apparatus forspreading roong-cement upon roofs evenly,.quiclrly, and conveniently 5and it consists in the combination of the guiding and `pressure roller,the box or hopper, and the adjustable spreading-board, as hereinaftermore fully described.

A is the box or hopper which contains the prepared roofing. The rearend, a', of the box A-does not extend quite to the. bottom a2 of saidbox, leaving a space or opening for the` escape of the roong. Thisopening is closed by a sliding gate, awhich works up and down in groovedcleats a4, attached to the rear end of the box A, as shown in thedrawings, so that the owof the roofing may be regulated at pleasure.

If desired, a lever may be connected to the gate a3, and may extendforward, so that the said gate may be operated from the front of lettersof reference indicate like I the box A. B is a roller, which is pivotedto the arms C, projecting from the front side of the box A.

The roller B is grooved around its central part to `receive thetriangular strip of wood which is usually placed over the overlappededges of the felting, as hereinafter described.

To the sides of the box A, near its rear end, are attached two runners,D and E, the forward ends of which `are roundedoff, so that they mayslide easilyY along the roof. These runners project in the rea-r of thebox A, as shown in Fig. 1, and are grooved vertically on their innersides, near their ends, for the reception of the adjustablespreading-board F.

The board F is notched at the middle part of its lower edge for thereception of the triangular wooded strip usually applied to theoverlapping edges of the'felting, and it is held in place by the rod Gand thumb-nut H, which draw the ends of the runners D and E toward eachother, holding the said board F securely at any point to which it may beraised. This arrangement enables the apparatus to spread a layer of anydesired thickness overthe felting.

In using the apparatus the strips of felting are applied to the roof inthe ordinary manner, with their edges overlapping each other and with asmall triangular strip of wood I placed overthe seam. The Inachine isthen drawn along the seam, so that the said strip of wood` may enter thenotch in the roller BV and in the spreading-board F. The gate a and theboard F being so adjusted lthat the coating of cement may be of thedesired thick ness, a strip of felting wide enough to cover the seam isthen applied, and another coat of cement applied in the manner beforedescribed. For this purpose I generally use two machines, one, a fewinches wide, to coat the the seam with the first coating, and the otherso wide that the layer spread by it will extend a little past the middleof the adjacent strips of felting, so that when the apparatus has 'beendrawn along each seam the whole roof may be covered with a layer ofcement.

It may sometimes be advisable, and especially in this case withreference to the apparatus when made wide, to place another rollerdirectly beneath the bottom a'z of the hopper, so that the parts thatform the seam Inay be closely pressed together before the cement isapplied and the apparatus be supported by and car` ried upon these tworollers.

The apparatus may be moved by arms or handles attached to the sides ofthe box or hopper A in the usual manner.

I claim as new and desire to secure ters Patent I The combination of theguiding and pressure roller B, the box or hopper A, and the adjustablespreading-board `F with each other, substantially as described, and forthe purpose set forth.
